Application filed October 24, 1911. Serial No. 655,469.

To all whom it may concern:

Be it known that I, JAMES K. DIAMOND, a citizen of the United States of America. residing at 'Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Tools for .Clenching Belt-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention,'such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in tools for clenching belt fasteners and its object is to provide a simple and effective device that can be operated by means of an ordinary machinists vise or other like means,- and to provide the same with various new and useful features hereinafter more fully described and particularly pointed out in the claims.

My device consists essentially of a pair of pivotally connected clenching dies adapted to be engaged by the jaws of an ordinary machinists vise, supported therebetween and pressed toward each other thereby to clench the fasteners into a belt and having attached thereto suitable means for pivotally connecting the dies and for holding the fasteners spaced apart and in parallel planes between. the dies, and in various features of construction and arrangement as will more fully appear by reference to' the accompanying drawings, in which:-

Figure 1 is a perspective view of a device embodying my invention; Fig. 2 avertical section of the same held between the position for inserting the fasteners therein; Fig. 3 the same shifted to initial position for clenching the fasteners; Fig. 4 an end elevation showing the position of the parts at the close of the clenching operation; Fig. 5 a detailin plan view of one of the dies and a part of the holding means for the fasteners.

Like numbers refer to like parts in all of the figures.

1 and 2 represent the clenching dies which are preferably rectangular bars of steel and of substantially equal dimensions. Secured to one of these dies and extending along one edge of-the same is areceiving member which the, same.

' tive jaw of the vise.

extends above the plane of the working face of the dies to which it is secured and is provided with an upwardly projecting portion 4 recessed transversely at regular intervals to receive the fasteners. Extending through.

this receiver is a pivot pin 6 on which various parts are pivoted as hereafter described. The opposing die 2 is provided with arms 5 secured to its respective ends, which arms embrace the receiver and are slotted at rightv angles to the working face of the die to recelve the pivot pin 6 whereby the dies are pivoted to open and close about the axis of this pin and the jaw-2 will move bodily to- Ward and away from the jaw l and thus the jaws will adjust parallel to each other upon belts of various thickness when closed upon Extending through the slotted portion of the receiver is also a removable pin 7 spaced apart from the pivot pin 6 a suitable distance to properly engage the concave side of the crown of the fastener. To press the fasteners against this pin and'bring the same in alinement and with one member against the surface of the die l a presser bar 9 is provided having transverse slots with projections 10 therebetween extending into the slots of the receiver through which projections the pivot pin 6 extends whereby this bar is eccentrically pivoted with the projections free to turn within the slots of the receiver and engage the convex side of the crown of the fasteners opposite the pin 7 A spring 12 serves to turn this presser bar about the pivot and engage the projections with the fasteners as illsutrated in Fig. 3. To move the projections away from the pin 7 'an arm 11 is attached to the bar which swings into a recess 14 in the side of the receiver.

' To support the device in partially closed position between the jaws of a vise the outer side of each die is provided with a shoulder 8 to engage the upper angle of the respec- When the device is partially closed so that the die 2 rests against the other leg of the fasteners the device can be suspended between the jaws of a vise as shown in Fig. 3 and by closing the vise the dies will swing about the axis of the pivot pin and clench the fasteners through a belt as illsutrated in Fig. 4, and

when the jaws finally close upon the belt the slot in the arms will permit the jaw 2 to move bodily toward the jaw l and thus seat the jaws parallel upon opposite sides of a belt of varying thickness. v

To insert the fasteners in the device the i die 1 and receiver 3 are placed horizontally ance to readily insert the staples with the convex crown of the same in alinement against the projections 10 and with one member'of the fastener resting on the surface of the die 1. In this position the pin 7 is inserted freely within the fasteners.

The die 2 can be swung upon the opposite, legs of the fasteners and the devlce removed from the jaws of the vise. The springs 12 will now turn the presser bar about the pivot pin 6 and bring the projections against the convex side of the crowns of the fasteners thus securely holding them in accurate alinethe projections of the ment and in parallel lanes ready for the clenching operation heretofore described.

What I claim is j 1. A tool of the class described, comprising a clenching die, a receiver attached to the die and having transverse slots therein, a pivot pin andja removable pin extending through the slotted portion of the receiver, a presser bar having projections extending within the slots of the receiver and eccentrr cally pivoted on the pivot pin, and means for'rotating the presser bar about said pin.

2. A tool of the class described, comprising apair of clenching dies'adapted to be engaged by the jaws of a Vise, a receiver at-- tached to one of the dies and having a portion recessed transversely, a pivot pin extending through the recesses of the receiver,

a removable retaining pin also extending through recesses of the recelver, a presser bar having projections extendin into the slots of the receiver and eccentrically piv oted on the pivot pin, and a spring to move presser bar toward the removable pin.

3. In a tool of the class described, a pair of clenchin dies pivotally connected, a receiver attac ed to one of the dies and having transverse recesses therein, a pivot pin and a removable pin extending through the recesses of the receiver, a presser bar having projections extending into the slots of the re-' ceiver and mounted on the pivot pin, a spring engaging the presser bar to move the projections toward the removable pin, and an arm. on. the presser bar to move the projections away from the pin.

4. In a tool of the class described, a pair of clenching dies, a receiver attached to one to the presser bar and adapted to enter the recess'and a spring to turn the presser bar toward the removable pin.

5. A tool of the class described comprising a clenching die and a receiver adapted to be held horizontally .by the jaws of a vise, a second clenching die pivoted to the receiver to swing freely to vertical position,

said dies also provided with shoulders to engage the vise, whereby the dies are suspended between the jaws of the vise in oppositely inclined position, and are closed to vertically parallel position when closed by the vise to clench the fasteners;

6. A tool of the class described, comprisinga clenching die and receiver adapted to be held horizontally by the jaws of a vise, a second clenching die pivoted to the receiver to swing freely to a vertical position, a pivoted member adapted to enter the receiver and engage fasteners therein and an arm attached to said member and adapted to be engaged by the said jaws of a vise when the dle and receiver are held horizontally therebetween and means for suspending the dies between the jaws of a vise with said arm out of contact therewith and the die in partially closed position.

7, A tool of the class described, comprising a pair of clenching dies pivoted to each other, a receiver having transverse slots, a retaining in extending through the slots, a presser ar pivoted to the receiver and having projections adapted to swing into the slots and toward the pin, an arm on the bar to swing the projections away from the pin, a spring engagin the bar to swin the projections toward tfie pin and shou ders on the dies to engage the jaws of a vise and suspend'the dies between the same.

8, In a tool of the class described, a pair of clenching dies shouldered on the outer sides to engage the jaws of a vise and suspend the dies therebetween, a receiver attached to one of the dies, a pivot pin in thereceiver, arms attached to the other die and,
